PIANO-ACTION RAIL-SUPPORT.

Specification of Letters Patentv Patented Sept. 10, 1907.

To all whom it may concern:

Be it known that we, WILLIAM C. VooEL and HARRY K. SNELL, citizens ofthe United States, both residing at Rockford, in the county of Winnebagoand State of Illinois, have invented a new and useful Improvement inPianoAction Rail-Supports, of which the following is a specification.

This invention relates to an improvement of a piano action for which theapplication for Letters Patent was filed January 6, 1906 and givenSerial Number 294,897.

The improvement relates especially to means for hinging the lower leverto the vertical action bracket.

The object of the invention is to reduce the amount of labor, andmaterial required and also the amount of space occupied, so that theinvention can be used upon a close scale where .the various parts of apiano action are crowded closely together.

A further object is to increase the strength of the connecting partsbetween the lever rail and the action bracket by casting them in onepiece and by reducing the number of pieces more room is gained as they00- cupy less space. The amount of bushing required is reduced and thereis also a saving of time and labor in making and fitting the partshereinafter shown and described.

The invention consists in the novel features of construction describedin the specification, pointed out in the claims and shown in theaccompanying drawings, in which,

Figure 1 is a transverse section through a lower lever rail, showing aportion of a vertical action bracket and showing in side elevation theparts connecting the lever rail and the bracket. Fig. 2 is a section onthe line 22 of Fig. 1. Fig. 3 is a perspective view looking from therear and side of a plate. Fig. 4 is a face view of the same plate. Fig.5 is a perspective view of a link to connect the plate and the action ofthe bracket, the bushing being omitted.

In these drawings 1 represents the vertical action bracket and 2 thelower lever rail, which parts are shown and described in the applicationfor patent above referred to and 3 represents a plate which is securedby screws ,upon the lever rail 2. This plate is provided with upwardlyand downwardly extending lugs 4 arranged in pairs and the upper pair oflugs have formed upon their rear faces projecting shoulder portions 5,which overhang and rest upon the upper face of the lever rail 2.

Two bifurcated links 6 are provided and the nonbifurcated end of eachlink is perforated and the perforation is provided with a suitablebushing, 7. These 3 and are pivotally held in place by pins 8 which passthrough the lugs and through the bushing 7. The vertical action bracket1 is also provided with perforations in vertical alinement with eachother in which are placed bushings 9 and the bifurcated end portions ofthe links 6 straddle the said action bracket and pins 10 pass throughthe said links and through the bushings 9 and pivotally connect thelinks to the action bracket.

It will be obvious that this construction pivotally connects the lowerlever rail to the action bracket and permits the upward and forwardmovement described in pending application.

Having thus fully described our invention, what we claim as new anddesire to secure by Letters Patent, is:

1. In a piano, the combination with a lower lever rail and a verticalaction bracket, a plate carried by the rail and having two pairs oflugs, links each having a bifurcated portion, the non-bifurcated endportion of each link resting between a pair of the said lugs, and thebifurcated pivot-ally connecting said links to the plate and to theaction bracket respectively.

2. A device of the kind described comprising in combination, a lowerlever rail, a vertical action bracket, a plate having" upwardlyextending and depending lugs arranged in pairs, the upper lugs havingshoulders formed thereon, said shoulders overhanging and resting uponthe lever rail and links each bifurcated at their forward ends, thenonbifurcated ends of the links being pivoted between the lugs, andtheir bifurcated ends straddling the action bracket and being pivotallyconnected thereto, as and for the purpose set forth.
